The ‘Ancient Harbour Parasequence’: Anthropogenic forcing of the stratigraphic highstand record

Unique chronostratigraphic similarities are observed in recent geoscience literature on ancient Mediterranean harbours. From these empirical port data a clear pattern of millennial anthropogenic forcing, marked by a fining-up sequence, can be discerned in coastal stratigraphy. The stratigraphic peculiarity of this artificial, or human-modified, parasequence leads us to define a new working model: the Ancient Harbour Parasequence.
